Is /u/ the new /v/?
I'm not sure I follow
Of course not, /u/ is actually /u/ related.
DEEN is saving anime, what are you talking about?
/u/ is the new /v/ of /a/ in /y/.
You mean the new shitposters on /a/? No, they always been here, but now that they have a new yuri-harem anime they are a bit out of control
If by that, you mean it's shit, then yes.
